Enhancing strength without sacrificing ductility in medium-carbon multiphase bainitic steel through increased intercritical annealing temperatures

open access: yesJournal of Materials Research and Technology
In bainitic steels, enhancing strength often comes at the expense of ductility. In this paper, a medium-carbon multiphase bainitic steel was produced through intercritical annealing (IA) at various temperatures, followed by isothermal bainite ...

Achieving ultrafine martensite-bainite duplex microstructures by combining prior cold deformation with chronological control of phase transformation in GCr15 bearing steel

open access: yesJournal of Materials Research and Technology
In this work, a strategy is proposed by combining prior cold deformation with chronological control of phase transformation to achieve ultrafine martensite-bainite duplex microstructures in GCr15 bearing steel, which is the specimens with 0∼45 % prior ...
